STM8S103的三路PWM波形

博客是个不错的记事本　把我怕忘掉的，都记下来

STM8S物美价廉，TIM2可同时产生三路PWM波形来,最快可达5MHZ

#include "stm8s.h"

uint16_t CCR1_Val = 500;
uint16_t CCR2_Val = 250;
uint16_t CCR3_Val = 100;

static void TIM2_Config(void);

void main(void)
{CLK_HSIPrescalerConfig(CLK_PRESCALER_HSIDIV1);//16/1=16MHZ
 
 TIM2_Config(); 
 
 while (1)
 {}
}

static void TIM2_Config(void)
{
 
 TIM2_TimeBaseInit(TIM2_PRESCALER_1, 200);

 
 TIM2_OC1Init(TIM2_OCMODE_PWM1, TIM2_OUTPUTSTATE_ENABLE,CCR1_Val, TIM2_OCPOLARITY_HIGH);
 TIM2_OC1PreloadConfig(ENABLE);

 
 TIM2_OC2Init(TIM2_OCMODE_PWM1, TIM2_OUTPUTSTATE_ENABLE,CCR2_Val, TIM2_OCPOLARITY_HIGH);
 TIM2_OC2PreloadConfig(ENABLE);

         
 TIM2_OC3Init(TIM2_OCMODE_PWM1, TIM2_OUTPUTSTATE_ENABLE,CCR3_Val, TIM2_OCPOLARITY_HIGH);
 TIM2_OC3PreloadConfig(ENABLE);

 TIM2_ARRPreloadConfig(ENABLE);

 
 TIM2_Cmd(ENABLE);
}

#ifdef USE_FULL_ASSERT

void assert_failed(uint8_t* file, uint32_t line)
